Definitions
- the invention relates to hardware items such as a splice plate, a hanger bracket, and a track support which are used to join together and support sections of monorail track.
- Such tracks are usually formed in a particular cross-section in order to provide a horizontal top rail section for supporting a carrier cell, as well as several vertical sections against which the carrier cell is braced in order to remain balanced on the top rail section.
- the track itself may be formed of extruded aluminum in straight or curved sections which must be linked together in order to construct a track path. When joining the sections together, it is important that the gap between the sections be kept to a minimum and that the top surface of adjoining track sections be absolutely level with one another.
- the track sections must also be mounted on supports which are attached to the floor or hung from the ceiling in order to position the track path at the proper height above the factory floor.
- the supports are usually custom designed to support the monorail track and thus add considerable expense to the overall system.
- a track splice for monorail track is designed to draw adjacent rack sections together in order to minimize the gap between the sections. Adjustment means are provided of the track splice so that the top rail sections of two adjacent tracks may be leveled with respect to one another to provide smooth carrier cell travel on the finished track.
- a hanger bracket for attaching the monorail sections to a support structure is provided which attaches to the monorail track by a quarter-turn motion. As a result, the bracket does not require the use of bolts which pass through the bracket into the track and the track does not have to be pre-drilled in order to receive the bolts.
- the supports which attach the track relative to the floor or ceiling are commercially available rather than being custom designed and are thus less expensive than prior monorail track supports.
- FIG. 1 is an exploded perspective view of two track sections and a splice plate according to the invention.
- FIG. 2 is a side sectional view of a splice plate attached to a track section.
- FIGS. 3 and 4 are top and side views, respectively, of a cam bolt used with the splice plate of FIG. 1.
- FIG. 5 is a perspective view of a hanger bracket.
- FIG. 6 is a side view of a hanger bracket coupling a track section to a floor support.
- FIG. 7 shows the steps of attaching a hanger bracket to a track section.
- FIG. 1 shows a splice plate generally designated by the reference numeral 10.
- the splice plate 10 is shown joining together two track sections 12 and 13.
- Each track section comprises an upper rail 14 having an upper shoulder 18, a lower rail 16 having a lower shoulder 20, and an intermediate web portion 17 joining the upper and lower rails together.
- the upper and lower shoulders 18 and 20 are each separated from the web by an undercut 19.
- the splice plate 10 is generally rectangular in shape and includes eight apertures, 21 for receiving through-bolts 22 which attach the splice plate to the two rail sections,
- the splice plate also includes two pilot holes 23 which receive two cam bolts 24 which are used to minimize the gap between two joined track sections.
- the splice plate also includes four adjustment screws 26, two of which are located along the top edge 27 of the splice plate and seat against the upper shoulder 18 and two of which are located along the bottom edge 28 and seat against the lower shoulder 20.
- the web portion of the track section ends are pre-drilled in a pattern of holes which corresponds to the holes in the splice plate so that the through-bolts 22 may be passed through the plate and the web.
- the web portion also includes non-circular holes 31 formed with straight sides 32 which receive the cam bolts 24, best seen in FIGS. 3 and 4.
- the cam bolts include an eccentric cam lobe 33 which fits into the non-circular hole in the track and a threaded shaft 37 which is received by the pilot holes in the splice plate.
- the splice plate In order to join two sections of track together, the splice plate is first assembled to the abutting ends of two track sections by hand-tightening the eight through bolts 22 to bring the splice plate and the two track sections into general alignment.
- the cam bolts 24 are then turned causing the flat face 35 on the cam lobe of each bolt to bear against the straight sides 32 of the non-circular holes to bring the two sections together and minimize the gap therebetween.
- Positioning the flat face 35 of the cam lobe against the straight side 32 of the non-circular hole provides tactile feedback to the installer that the cam bolt is in the home position and that the maximum travel of the two track sections toward each other has been achieved.
- the flat face 35 also acts as a locking feature to maintain the cam bolts in the home position.
- the nut 36 on the threaded shaft 37 of the cam bolts are then tightened to hold the cam bolts from moving out of the home position.
- the lower adjustment screws 26 are then used to force the lop edge 27 of the splice plate into contact with the upper track shoulder 18.
- the upper adjustment screws 26 are tightened to bring about the desired compensation.
- the remaining adjustment screws 26 are then tightened to prevent the two track sections from slipping vertically.
- the eight through bolts 22 are then finally tightened to secure the joint between the two track sections.
- the hanger bracket is generally designated by the reference numeral 40.
- the hanger bracket includes a tubular body 41 which acts as a stand-off between the head 42 of the bracket which attaches to the track and the foot 43 of the bracket which attaches to a support.
- the head of the bracket is generally rectangular in shape and is characterized by two flanges 45 each of which has a truncated or rounded corner 46.
- Four threaded holes 47 are formed in the head of the hanger bracket to receive set screws 48 for securing the bracket to the monorail track as described more fully below.
- the foot 43 of the hanger bracket 40 is generally square and includes a threaded hole 50 in each corner thereof to receive bolts 51 to attach the foot to a support member.
- FIG. 7 shows the process of attaching the head 42 of the hanger bracket to a monorail track.
- the head is placed against the web 17 of the track in a position with the flanges 45 on the left and right sides of the bracket with the set screws 48 not yet installed in the two threaded holes 47 which are located in each of the truncated corners 46.
- the bracket is then rotated 90 degrees in a clockwise direction to position the flanges in the top and bottom undercut 19 formed between the shoulder and the web of the track.
- Set screws 48 may now be threaded into the holes 47 in the truncated corners to prevent the head from rotating counterclockwise since the set screws will interfere with the shoulders 18 and 20.
- the four set screws 48 may then be tightened against the web of the track to prevent the hanger bracket from rotating counterclockwise thus locking the hanger bracket in place.
- the hanger bracket can be securely attached to the track section without the use of bolts which pass through the track thus eliminating the need to pre-drill holes in the track.
- the truncated corners 46 of the flanges allow the bracket to be twisted into engagement with the undercut of the track at any location along the length of the track without having to insert the flanges into the undercut at one end of the track and then thread the head of the bracket along the undercut to the desired position along the track.
- tripod supports 52 shown in FIG. 6, which are sold for other purposes.
- Each tripod support includes a tripod foot section 53, a body 54, and a coupling 55 which attaches to the hanger bracket as described above.
- the tripod supports are shown in an orientation which would be used to support the monorail track on a floor, those skilled in the art will realize that the tripod support or an adaptation thereof may also be used in an inverted position to support the monorail track from a ceiling or other overhead support.
